One of the earliest routes to the summit of Yr Wyddfa (Snowdon)

The Snowdon Ranger is believed to be the earliest of the six main routes to the summit of Yr Wyddfa (Snowdon).

The route starts at the shores of Llyn Cwellyn, giving the path its Welsh name of Llwybr Cwellyn (Cwellyn Path). It climbs gradually to the slopes of Moel Cynghorion and over to Bwlch Cwm Brwynog before ascending steeply above Clogwyn Du’r Arddu and merging with the Llanberis Path to the summit.

Why this path?

Reaching the summit of Yr Wyddfa (Snowdon) is a challenging undertaking. The Snowdonia National Park Authority classifies all of the routes up Yr Wyddfa (Snowdon) as hard, strenuous routes. A good level of fitness is required, and navigation skills are essential.

The Snowdon Ranger Path is one of two paths ascending the western slopes of the Yr Wyddfa (Snowdon) massif. It can be an alternative to experienced walkers and offers fantastic views of the lesser-seen parts of the area.

The Route’s Name

The Snowdon Ranger Path is the only route to the summit of yr Wyddfa (Snowdon) with entirely different names in Welsh and English. Its Welsh name, Llwybr Cwellyn (Cwellyn Path), is most likely named after the route’s starting point on the shores of Llyn Cwellyn.

However, a mountain guide called John Morton was the inspiration behind the route’s English name. Morton, who called himself the ‘Snowdon Ranger’, had built an inn on the shores of Llyn Cwellyn during the 19th century, where he would set off on guided hikes to the summit of Yr Wyddfa ( Snowdon). Today, the inn operates as a youth hostel and can be seen opposite Llyn Cwellyn’s car park.

Mythology and folklore

The route will offer fantastic views down towards Llyn Cwellyn, where the slopes of Mynydd Mawr ascend gracefully from the lake’s western shore.

Coniferous forest makes up the lower foothills of Mynydd Mawr. However, on the right, towards the far end of the lake, you might notice a prominent crag where the forest comes to an end. The rock is known as Castell Cidwm (Cidwm’s Castle). Legend tells that this was the home of Cidwm—a giant who lived in a cave within the rock.

As you near Bwlch Cwm Brwynog, a lake will come into sight on your right called Llyn Ffynnon y Gwas. The name translates to ‘the lake of the servant’s spring’, and it is thought that it was named after a shepherd who drowned in its waters while washing his master’s sheep. The remains of an old stone sheepfold can be seen on the lake’s northern end – perhaps proof that there is truth behind the story.
